ELECTRIC Application led August 14, 1924. Serial No. 731,99L`` To all whom 'it may concern."

Be it known that I, SOCRATES A. Xrrras, a citizen of the UnitedStates, 'residing at Pittsburgh,l in th-e county of AlleghenyT and lState of Pennsylvania, have invented certain new and useful Improvements in Elec-Y tric Fans, of whichthe following is a specication.

My invention relatesto electric fans.

Thelobject of the invention is to provide a device which will produce a large amount of air blast. and to have no visible moving parts which renders the fan absolutely safe against accidents.

A further object of the invention is to provide a device which will cause acontinuous flow of air inall directions and to take the place of the ordinary .buzz oscillating fans and their crude and intricate .mechanism as in my invention there are only two bearings and no interior working parts liable to get out of order.A Y

A further object is to provide means whereby the blast may'cbe vregulated so as to blow in any one or more particular' directions when it is not desired'to have the blast to discharge in all directions,

v which directions-includes vertically, hori-v zontally and any angle of blast discharge between the oints designated.

' Further. o jects and advantages will be )more fully described herein and specifically pointed out in the claims hereunto annexed recourse being had tothe accompanying drawings forming a part of this specification in which Figure 1' is a view. of the complete fan. l AFigure 2 is a view of the upper portion of thefan showing the blast regulating or cut oifplates on the perforated casing orl sphere.

gure 3 is a perspective view of one of y the blast shut oii or cut 'out plates.

above the ring or oblique disc.

Figure 7 is a perspective'- view-of the impellers.

Figure 8 is a fragmentary cross section of n oblique annulus or ring with its wings or.

v stand of the apparatus arranged inthe ordinary manner.

2 isa vertical motor adapted to have a vertical shaft, also, and tov drive thehereinafter described rotor with its wings or impellers.

3 are the brush terminals of the 'motor and are adapted to be attached to wires leading to an electric supply. i

4 are the lubricating oil cups, and 5 is the vertical motorI shaft `before mentioned.

6 is' a switch, Figure l, for regulating the speed of the motor in the usual manner.

Mounted on the upper end of the motor 2 is a spherical perforated cage or shellentirely enclosing the hereinafter described wing or iinpcller mechanisn'iv which constitutes the blast making fan or rotor, and is in two parts, the upper 7 and the lower portion 8 suitably vunited as at 7, in Figure l.

The shaft 5 passes through the sphere or globe 7 8, its lower end being suitably mounted .for rotation in the step bearing 9, dotted lines, thc upperend of the shaft rotates in the bearing lOin the topv portion 7 ofthe perforated cage or spherical shell.

11 is au ornament, said ornament also forming points of attachment for Ithe hereinafter described shut olf plates.

In order to permit the'blast to be discharged from the perforated globe shaped i 'cage'or shell, the perforations 12 are out therein and are arranged radially from the top of the cage downwards to near the cen tre 7 and covers the entire surface.-

The perforations 12 vary in width and increase as. they approach the centre' 7i ofv the globe 7--8.

It will be seen that the perforations permit the blast to be'freely discharged from the entire surface, upwards, downwards and and at any inclination.

'13 .are perforations. or blast orifices V formed by .the belt'or horizontal bars 13a and the radial staggered bridge bars 13h 'thus forming elongated or rectangular blast eXit passages.

As shown in Figure 1, twokinds of per-l forations are placedson the sphere or globe' but the entire surface of the ball like cage may be perforated with only one style, that is, either the radial spaces `12 or the girth or horizontal slots 13. 'i

Upon the shaft -5 at or near the central portion of the cage, globe or sphei'e7-8, is placed a sleeve or collar 14 having an angular or bevelled portion 16. 15 is a similar sleeve or collar having a bevelled end 16 corresponding to the bevel of the sleeve 14.

Both sleeves are secured to the shaft 5 by the set screws 17 and are adapted to be separated'a short distance so as to form a space for the clamping 0f the centre` 18 of `the ring or annulus '19. Therefore, when said centre 18 of the ring or gyrator 19 is firmly clampedby the parts 14 and 15 forming a collar, the ring is held at an angle,A (Figures 4 and. 6), or 'in an oblique position, as shown. disc 0f 'metal is cut so as toform a series of blades, wings or impellers, usually four, and to accomplish this, the circular disc is cut into four parts which are bent upwards and downwards to form the blades20.

The cut out segments above mentioned are smaller than the actual segments capable of being cut from the circular `disc thus producing the 5 and 7.-

Two of the spokesv or arms 20, *Figures `blades lare bent upwards. and

two bent downwards, as shown, and the blades are preferably made -to assume slight angles to each other. l.

lReferring to Figures 4 and 6, it will-bey seen that the cuter peripheries 21, .shown -by dotted lines. of the upper Wings or blades 20 form a circle as do'the lower blades or wings, Figure 4, therefore they form a portion of two discs intersecting eac-h other at right angles. y

- The manner of operation involving the oblique or wabble motion of the ring 1-9 and its blades or wings -20 is, that by the peculiar motion .of the rotating parts, the air is forced' upwards upon the rising of the ring to its highest position and forced downwards by the lower blades and the alternate and rapid reversals of motion forces a large quantity of air in all directions.y

1n this invention there is more'blast for less blade area as the air is slightly cornpressed or retarded and then discharged there being no ineffective or dead surfaces as is common in fans of the propeller disc variety. A

In order toV provide means whereby the blast may be directed or restricted to a certain In order to form the ring 19. a-

24 at their upper or lower portions the eye or hole ofwhich are adapted to be inserted over the boss 25 and. the portion 26, Figure .1n this. manner the plates 22 and `23 can be rotated entirely around all portions of the sphere 7-8 so .that a certain number of the perforations 12 and 13 can be closed or cut out and the blast of air directed at a given point or points at will.

The plates for convenience, are provided `with knobs 27 for facilitating the movement thereof.

In the fan described, the motor by, which the beforementioned wings or blades are driven, is vertical so that it is not necessary for the inotor to assume any angular posi-- tion as is done in the ordinary disc or buzz fan and which is effective only in small areas: The uses of my invention are more varied than'the ordinary propeller fan and is better suited for commercial uses besides being absolutely safe where there are children as there is no Idanger of severed or injured fingers.

For drying ladies hair after shampooing, the fan `can be held close -to or against the head without inconvenience or danger and have the' blast to blow in all directions.

At. dining tables, lunch counters and other places, the blast is directed to each personalike and eliminates flies for a large area around said tables or counters,

vwlIn the directing of the blast upwards,

downwards as well as as at all. angles,'the quiescent heated air at the ceiling of a room is dislodged and permits the circulation of fresh air.

The amount of electric current requiredy to operate my device is less than that required for the ordinary type of fan to produce a greater amount of effective blast.

I may dispense with the angular positioning of the fan br blast element and place it atright angles to the axis of rotation.
